error 0x80004001 when copying file OFFICE.ODF.x64

I want to get rid of some of my files as I do not have any space left. I am copying all of my files bit by bit and pasting them onto my Toshiba External Hard Drive. For the moment I have done a Search for OFFICE and am now copying them to Toshiba HD. My search found lots of double/triples of the Office files totalling 2,979 files in all which is 1.08GB. I am not sure that I need every copy and if I need to keep any files for 64 bit system, as I run 32 bit System. Cannot attach the list of files as there are too many and they depasse the size limit. Size is 4.82 MB (5,058,752 bytes).

The function has stopped as I received a message saying "An unexpected error is keeping you from copying the file (OFFICE.ODF.x64)

ERROR CODE 0x80004001: Not implemented file is OFFICE.ODF.x64.

By the way, do I need to keep this file as it is for 64 bit and I have 32 bit system?"

Thank you for any help available.
